Stihl Trimmer Won’t Stay Running; not Idling. Quick Fix  

I don't feel good, but this guy make my day, bless 🤣🤣🤣 for you.

This guy is gold! Thanks for the help

FS 55R - this worked for me. Would die at idle speed; pulled the screen, burned the crud off. Replaced, started, idled just fine. Thx

I like this guy. Trying this with my weed eater tonight...

How do you turn the carb back to factory setting?

Well, a guy at work gave me a “56” that didn’t run right for parts. Turned out to be an FS70 with FS56 plastics on it. No big deal I’m getting a new one and a source of spare parts is nice, but it doesn’t idle right. Might try this. On a side note, my FS56 has ran for years, and I mean 6+ that I know of, never had the spark arrestor taken off or cleaned and still runs good. Guess I got lucky

You my friend have a cool sence of humor!👍👍👍👍👍👍👍👍👍 You are a great teacher Mack!

I hope this was it. I’ve been having the same problem with both my km91r and br600. It’s 11 at night and I just went down to my basement and removed the screens from both of them. Both very black. I don’t think my wife would appreciate me starting them up right now 😂 but fingers crossed for tomorrow. They would both run ok when starting from cold but the minute I stopped them and pick them up a few minutes later they’re both running like crap. It’s not the amount of oil because I measure it to the drop and I also just changed all the fuel filters, air filters and spark plugs. So I’m really hoping this is it.

My FS 240 was having problems past idle. This man is 100 percent correct. Burned-out the carbon from the exhaust. Works like a charm.

Thank you so much!! 100% spot on.

How about some gun barrel spray cleaner like hopes or ballistol and spry it on and let it set for a few minutes and then use a tooth brush to brush all the carbon off.

04:35 i usually tighten things up until I strip the thread then I back it off half a turn then I know it’s tight I work in the oilfield

Okay I just bought an FS 111 edger. The thing will not stay running. Brand new. I’m not sure STIHL the way to go

Learning as i go

Brand new air filter and completely cleaned spark arrestor and my STIHL FS45 still wont idle...

Clean the spark arrestor screen. Clean the air filter. Thanks.

Thanks for letting me know this All the best.

Thank you for your advice it worked great

Sparkilator!!! Haha.

Great advise and very entertaining. definite LIKE here.

What is the name of that torch? I don't have one

Thanks bro.

Awesome advise. Thanks alot.

Bruh is hyped tf up

thanks 😮

It’s not a sparka-later 😂

It would have been a great video if it were not for all your histrionics!

Carhart is not made in USA anymore dude, with a couple of exceptions

Stay off the crack...I wanted to know why my weedeater don't stay idle

Didn’t know this thing existed… pulled it out, hit it with torch to burn the carbon, and now she runs like new. Thanks!

Jeez your tiring to watch. But great tips. Cheers mate👍

THIS MAN REMINDS ME OF A HIGHSCHOOL GYM TEACHER OR SCIENCE TEACHER MAKES RU-vid MORE FUN 👍🏼🤣

I bought a new fs91r and it’s not idled right from the very beginning. It will die about half the time at idle and fire back up and also has a small sputter at full throttle. 🤷‍♂️

So I've gone and messed around with the factory settings on my stihl FS75 weed trimmer... Can someone please help me put it back to the normal settings so she's purring like a kitten again 😢

Very entertaining & enlightening. Keep being you...Funny as F--K

Little advice for your next vid, lay OFF the speed or hire a real comedian lol.

Id love to work with this guy. I just need him to yell more

Good info , but this guy drinks to much coffee mix with cocaine! 😂

What if my fs110r isn’t wanting to turn on right away could it be one of those problems?

Mine was dirty exhaust screen. It’s that Stihl 2 cycle oil the dealer scares you into buying. Cleaned my exhaust screen and switched to Echo oil. Much mo better!

Finally a small engine guy I who can turn the most boring topic into entertainment. Now just to see if these fixes sort out my idle issues.

Mine is doing this and it doesnt have the screen in the muffler

Is this that senator from Pennsylvania??

Stop talking and get to the point!!!

Was hoping this would solve my problem. Unfortunately it did not. I have replaced fuel filter, air filter and spark plug. New gas. When I pulled the spark arrestor out, it was clean as a whistle. So my next step is to buy a carburetor. Good video!

Mine won’t idle. Screen and filter are both clean. It’s pretty obviously a carb issue.

Thank you muchly!!!

FS86, it's a fuel issue

You’re amazing

will this work if it starts, then died when throttling, and now it won't start at all? . I don't know what i'm doing

Obnoxious!

My FS56RC was acting up. Replaced the carburetor, still was acting up. Watched this video, and torched my exhaust screen. Runs like a charm now, thank you.

I have a fs250 with a brand new muffler and a brand new carberator and air filter,wont stay running.I garauntee its not the air filter or spark arrestor,so what could it be?

I have a fs111 and since i remove the spark arrestor its like getting a new engine! But i change to amsoil saber and forget about having that problem.

Great advice. I had this issue with my stihl. I was surprised how little carbon build up causes this problem. Saved $$ not having to send for a service. 🖒🖒🖒

What you won't here from a gas powered tool manufacturer is this: SPARK ARRESTORS SUCK, but are required as so-called safety items. My weedeater, chain saw, and hedge trimmer all started to fail to operate or start. Once I removed the spark arrestors, they all run like new!!

My fs 85 R is new its the second time am using it

This guy is AWSOME!! Wouldn’t want him as a neighbor though, to high strung! 😆

This was the perfect adhd level presentation. If only every instructional was so performative yet concise lol

I was looking for my big hammer when I remembered to check you tube! It was the sparkulator 🤣. Thanks

You're wearing me out just watching you! Maybe take a couple double shots of bourbon before you make your next video! lol

Mines been running like shit since it was brand new. Took it apart cleaned it put it back together with fresh gas and still runs like shit. Ive had ot 5 years and still runs the same as new.

Brother you are sooo original. I love the way you explain. Thank you. God bless you.. have a Feliz 5 de mayo.. gardeners like me appreciate you advice.. thanks again y si. Feliz 5 de mayo..

I have an older FS40 Trimmer that was hard to start, if started, so I purchased a Carburetor, luckily it was for a newer model, and I returned it. I removed the Spark Arrestor, put fire to it, removed the carbon deposit, and now it runs like a champ. I did have to adjust the idle control screw to eliminate the staling when the trigger was released. Not often does one find a DIY Video that is entertaining and informative. Thank you...

Got a weird one. My FS 40 runs like a champ for about 15-20 minutes and acts like it ran out of gas. But viewing show still a third of a tank. And it will crank and idle just fine forever, but when you touch the throttle is dies. Replaced air filter last year as it wouldn't run, but would run without air filter. New filter resolved that issue. This new issue has me scratching my head raw. I thought wow at 1st. What the heck is a spark arrestor? Took mine off, not really that black, but burned it a few times and blew it off and clean as new. No luck... Thinking new carb is my next option. But why does it run for 15 minutes before I have the issue? And if I wait a day, it will run again for about 15 minutes. So weird.

My stihl weed eater doesn’t have a screw for the arrestor, it’s a 16 socket. When I pulled it out I don’t see a screen on it. It’s just a short stubby screw. Threads on one side and just a flared end on the other (exhaust)

I’ll buy you a cup of coffee my brother! I was at wits end, and you saved the day!

Pulled this video up at work because I had this problem but much worse, took a minute to burn away all that black shit but it works great now.

How do I reset my carb back to the factory setting ? I wish I saw this before toying with it 🤦🏽‍♂️

Never knew what a spark arrester was until your video ------ I cleaned it and that was the problem! Thx!

This do happen but i work on them for a living and see maybe 2 a year that this is the problem.

Thanks for the knowledge but you’re a lot bro

I replaced the filter but FS 91r still doesn't want to run at idle, every time I stop to reload string it dies.

Dude. If the steps weren’t so easy, I wouldn’t have retained anything because I was laughing so much. LOL

Never would thought the spark arrestor was the problem, thanks, my FS55 started right up and idled fine

Sooo dramatic 🤣

This like them kids show where they want you to say what they say

Hello from the future, I’m excited to try this. Thanks! 💞🥳

Worked like a charm.

Amusing dude. Thanks it worked for my Stihl.

The guy is funny I'm taking his advice

You are hilarious! Thanks for the info.

I now try this and it's working good for me

Ok geeze, you don't have to yell at me like a cracked out Italian. Some funny jokes but man, couldn't handle the in your face yelling by halfway.

You’re awesome! You really cheered me up

Bruh.... Id need a shit ton of caffeine 2 have his energy,lol

Someone buy this man a cup of coffee! Had me back up and running in under 5 minutes. Spark Arrestor was clogged.. The Still dealer is half hour away so I burned it out as well, a shot of Clean Streak cleaner, and compressed air.. she's purring like a kitten.

I had a good time 😂 Super Landscaper 😂

Thank you so much I could not figure out what was wrong with my steel weed eater is always worked great but it had lost power and we couldn't figure out why my brother tried checking the gas make sure of course in the air filter in the primer ball and everything we could think of and it was the spark arrestor screen it totally fixed it in minutes so I'm very grateful thank you I have my weed eater back

Nice torch, where did you get it?

You’ve had enough coffee! 🤣🤣😊

you ARE ANNOYING

Thanks for the help, you are the man!

You're so silly! I'm gonna go check my sparkalator I mean spark arrestor right now.

Somebody buy this guy a cup of coffee ☕️ 😂!

Not on my fs 56 rc... runs 20 seconds and then dies

PUT THE COCAIN DOWN!!!! 🤣🤣🤣

🫶🏼 the energy

Bro..... You are funny af Thanks for the both informative and entertaining video

Mine is running like a toilet right out of the box…it’s got 15 minutes on it
